There are many web hosting sites online today and its very confusing to choose the right one. check dailyrazor.com its very flexible and you get full support to insert your ideas in your site.
May be what you are looking is a webhost that is powered by litespeed webserver i host one of my site at tmdhosting.com they are good in what they claim to provide. another site in hostguts.com very good but rate is slighly high (they have litespeed webserver and cloudlinux operating system so your website will outperform than the websites hosted at bluehost,hostgator)
Unlimited does'nt exist. Be realistic and know exactly what resources your site/s use. Then chose the type of hosting you need shared/vps/dedicated etc. There are many good hosts out there and find their review before chosing. good luck
Well .... Uptime, reliability, performance and customer support are some of the factors which must not be ignored during selection. There are many web hosts which provide good services e.g StartLogic, Dreamhost, Laughing Squid, IX Web Hosting, AN Hosting, HostICan and bluehost. Read reviews and if possibel, go for a trial for couple of selected hosters and compare the results as per your business requirements.
